Toxicity of atmospheric aerosols on marine phytoplankton [PDF]

open access: yesProceedings of the National Academy of Sciences, 2009
Atmospheric aerosol deposition is an important source of nutrients and trace metals to the open ocean that can enhance ocean productivity and carbon sequestration and thus influence atmospheric carbon dioxide concentrations and climate.

Examples of high performance liquid chromatography (HPLC) application in marine ecology studies in the northern Adriatic

open access: yesNatura Sloveniae, 2010
Photosynthetic pigments have proved to be useful biomarkers of the abundance, composition and physiological status of the phytoplankton biomass in the marine environment.

Effect of Polystyrene Microplastics in Different Diet Combinations on Survival, Growth and Reproduction Rates of the Water Flea (Daphnia magna)

open access: yesMicroplastics, 2022
Microplastic pollution is a problem not only in the marine environment but also in freshwater ecosystems. Water flea (Daphnia magna) is one of the most common omnivorous cladocerans in freshwater ecosystems.

Automated image classification workflow for phytoplankton monitoring

open access: yesFrontiers in Marine Science
Phytoplankton are fundamental components of marine ecosystems and play a critical role in global biogeochemical cycles. Efficient monitoring of marine phytoplankton is crucial for assessing ecosystem health, forecasting harmful algal blooms and ...

Long‐term exposure to increasing temperature can offset predicted losses in marine food quality (fatty acids) caused by ocean warming

open access: yesEvolutionary Applications, 2020
Marine phytoplankton produce essential fatty acids (FA), which are key component of a healthy diet in humans and marine food webs. Increased temperatures can reduce lipid and FA content in phytoplankton; thus, ocean warming poses a risk for the global ...

Terrestrial forcing of marine biodiversification

open access: yesScientific Reports, 2022
The diversification of the three major marine faunas during the Phanerozoic was intimately coupled to the evolution of the biogeochemical cycles of carbon and nutrients via nutrient runoff from land and the diversification of phosphorus-rich ...

Examining the size-specific photosynthesis-irradiance parameters and relationship with phytoplankton types in a subtropical marginal sea

open access: yesEcological Indicators, 2021
Through photosynthesis, phytoplankton initiate material cycling and the flow of energy through marine ecosystems. The structure of marine ecosystems is sensitive to the size of primary producers, and size-specific photosynthesis-irradiance (P-I ...

Marine phytoplankton primary production and ecophysiology using chlorophyll-A fluorescence [PDF]

open access: yes, 2007
Marine phytoplankton ecophysiological state and primary production measurements have typically been controversial due to potential impacts of measurement techniques.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

open access: yesIntegrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...
